To a-ZZ 'whom it may concer/1t:

Be it -known that I, MAXIMILIAN S. l-laoirrrn., a citizen of the Empire of Japan, and a resident yof Elites-Barre, Vin 4the county of Luzerne and State of'lennsylvania, have invented certain new and useful Improvements in Gravity Separators, `of which the following is a specification.

This invention relates to improvements in gravity separators.

The object of the invention 1s to provide a separator of the above character adapted to be used in classifying and separating materials comprising particles specific gravities. l

It is alsov an important object of the invention that the separator be adapted to efficiently operate for separating` materia-l into two different grades, that is,4 all objects inthe material having a specific ygravity above a certain degree being separated from the particles having a lesser specific gravity;

Other objects, and objects relating to details of construction, 'combination and arrange-ment of parts will hereinafter appear in the detailed description to follow. f

ln carrying out thepresent invention, it

is .contemplated to employ twoseparate currents of water, one of which is a constant current while the other is .a pulsating cur,- rent. rThe constant current of water Vand the pulsating current are soarranged-that the pulsating current serves 4to initially separate the lighter `particles from the heavier particles in the material being operated upon and the constant currentmaintains this separation a suflicient 'period so that the heavier material may be mechanically removed from the lighter material.

The invention is illustrated by way of'example in the accompanying drawings, in which Figure l is atop plan view of the separa- 1301'. I 1

Figure 2 is a vertical longitudinal-sed tional view of the same.

Figure 3 is a detailed view of the pulsating valve employed in connection with the apparatus.

Referring to the drawings more particularly, 10 indicates generally a tank which consists in the 'two side walls 11, a forward end wall 12 and a bottom 13 which isl formed with a conical shaped formation 15 terminating its lower end in a suitable opening which communicates with a drain of variousl `said pipe being equipped with a;

The grating 21 may consist in a plurality of bars 22 which extend transversely of the tanl and preferably the one end portion of the grating is sloped as at 23, and also the grating should overlap the partition wall as at 241 and extend downwardly as shown. The grating 2l is supported by bars 25, said bars extending between sides 11 of the tank. A hopper 27l is positioned at the forward end of the tank, its lower end being adapted to deposit grating 21K. An adjustablek valvemember 28 is provided at the lower end of the hop` material pass- Y the grating etween the extended portions 19 `of the per whereby to regulate the in from said hopper upon side walls 11 there is positioned `an inclined bottom generally indicatedv by they reference numeral 29, said ybottom terminating at its 1 lower end in an upwardly extending portion l30 which extends to a'point immediatelybe material vupon the neath the rear end ofthe grating 21. 'This' i `bottom may be provided at its rear end with a chute as indicated at 32 and above this' bottom there is positioned an endless belt 33 carrying blades 34. The belt is is rotated in the direction of the arrow 36 29 will-be carried to. the chute 82.

passed l .about al pair of rollersl 25.v Vhen the belt Above the belt or conveyor 33 there is j positioned a' partition wall 37 which is `adapted'to form a trough thereabove and saidy partition wall terminating at its lower :end in an upwardly extending portion 38 ywhich may be supported at its rear end by a cross member 39 and which may have a portion extending beyond the cross mem ber asl at 40, and said portion'being horizontally disposed as shown. A conveyor belt 41 is provided,l said conveyor belt being extended about suitable rollers L12 and lhaving blades 13 extending therefrom whe-reby upon the belt being moved in` the direc tion of the arrow 46 any material at the liu preferred form of my invention, I wish it to be understood, that I am aware of the fact that the construction, combination and ar rangement of parts may be changed by those skilled in the art wit-hout departing from the spirit of the invent-ion, as indicated yby the appended claims.

I claim scribed, a tank, areticulated platform within the tank, means whereby a material to be separated may be deposited upon said platform, means whereby a'pulsating cur rent of liquid may be directed upwardly and beneath said material and also rearwardly with relation to the tank, said pulsations of liquid being adapted to lift the material and whereby during the ,settling thereof and between pulsations the lighter'r particles of material may separate from the heavier particles, a partition rearward of the reticulated platform adapted to maintain the separation of the lighter particles from the heavier particles, and means whereby a counter-current of liquid may be es? tablished at the rear of the reticulated plat v form and thereby to insure the separation of said particles. f

2. In an apparatus of the character de* scribed, a tank, a reticulated p-latform within the. tank, means whereby a material to be separated may be deposited upon said platform, means whereby a pulsating current of liquid may be directed upwardly kand bey neath said material and also rearwardly with relation to the tank, `said pulsations of liquid being` adapted to lift the material and whereby during the settling thereof and between pulsations the lighter particles of material may separate from the heavier particles, a partition rearward of the reticulated platform adapted to maintain the separation of the lighter particles from the heavier particles, and an adjustable baliie plate hingedly secured to the forward end f said partition and adap-ted for transverse swinging movement with respect to said tank.

3.v In an apparatus of the character described, a tank, a recticulated platform `within the tank, means whereby a matera] l. In an apparatus of the character de-` to be separated maybe deposited upon said platform, means whereby a pulsating current of liquid may be directed upwardly and beneath said material, a partition rearward of the reticulated -platform adapted to'maintain the separation of lighter particles from the heavier particles, and means at the rear of lsaid partition whereby a counterlow of liquid may be established, for the purpose described. i

t. In an apparatus of the character de.- scribed, a tank, a reticulated platform wit-hin the tank, means whereby material to be separated may be deposited upon said platform, means whereby a pulsating current of liquid may be directed upwardly and.

beneath said material andalso rearwardly with relation to the tank, said pulsations of liquid being adapted to lift the material upon the platform and during the settling of said `material hetween they pulsations the lighter particles of material may separate p from the heavier particles, a partition rearward of the reticulated platform adapted t-o'maintain the separation of said material, a baffle hingedly secnred to the forward end of said partition, a supporting member above said baffle plate, a screw carried by said supporting member, and a connection between the free. end of said baliie member and screw whereby `said baliie mem# ber may be adjusted, for the purpose described.
